Re: Colour contrast of text in video content

I have done some further investigation and I have found the answer. The normative text of SC 1.4.3 refers to "The visual presentation of text and images of text..."

WCAG's definition of "image of text" is "text that has been rendered in a non-text form (e.g., an image)...", which would include video content.

It doesn't help that the Understanding page informally describes an image of text as "text that has been rendered into pixels and then stored in an image format", which would not include video content, since it is not an image format. That paragraph should have just pointed to the formal definition instead of paraphrasing it inaccurately.

Thanks to all who replied to my question - it looks like I was wrong (again).

Agree, this has been our take on 1.4.3 as well. Text in video, text in images/SVGs, etc all fall under 1.4.3.
